I just added Einstein@home to my projects using the "add project" feature in the BOINC program. I signed up with Einstein as a new user using the same email i use for Seti@home, and when it asked me for my name i used the same name i use here (Yanivicious). I don't see any evidence that the accounts are "linked" however. When i say linked i mean, i see that when i click on the name of many users here on S@H, it shows the different projects they are involved in and their credits in them etc.. on their profile page. Will i be able to see that once i earn some credits in einstein, or did i do this wrong? If anybody could tell me how I could tell i'd be grateful.

That feature doesn't depend on credits earned but on the number of connections to either project, as such the information gets shared between projects. So, if you've really used the same email address for both projects, you just need some patience. It may take a few hours/days.

The multi project stats are based on a third party site that does the work. Projects do not add a new user to their output for the third party stats sites until some credit has been earned for that project.
